Crashing on AMD iGPU (ring gfx_0.1.0 timeout)

Help
1

I have a hybrid graphics laptop (Lenovo 16ARX8) that works perfectly when in dedicated graphics mode. When I try to switch to hybrid graphics my desktop will crash after a few minutes with the error:

niri[2643]: amdgpu: The CS has cancelled because the context is lost. This context is innocent.
kernel: amdgpu 0000:05:00.0: amdgpu: [drm] *ERROR* Failed to initialize parser -125!

Similar issues I can find online all relate to ring gfx_* timeout but none of their solutions have helped so far.

My config for hybrid graphics is the following:

# 16ARX8.nix
{ config, pkgs, lib, ... }:
{
  services.xserver.dpi = 189;

  boot.kernelModules = ["amdgpu"];
  services.xserver.videoDrivers = [
    "amdgpu"
    "nvidia"
  ];

  hardware = {
    graphics.enable = true;

    amdgpu.initrd.enable = false;

    nvidia = {
      package = config.boot.kernelPackages.nvidiaPackages.latest;
      open = false;
      modesetting.enable = true;
      nvidiaSettings = true;

      powerManagement.enable = true;
      powerManagement.finegrained = true;

      prime = {
        amdgpuBusId = "PCI:5:0:0";
        nvidiaBusId = "PCI:1:0:0"; 

        offload = {
          enable = true;
          enableOffloadCmd = true;
        };
      };
    };
  };
}
  • Sometimes it crashes after a few seconds, sometimes minutes. Noting I do seems to affect how long it takes to crash
  • Sometimes it crashes GDM before I can even log in
  • I have tried using nixos-hardware as a reference but I can’t find any fix there
  • I have tried both 6.12 and 6.18 kernel packages
  • amdgpu.ppfeaturemask=0xfff73fff or any other feature masks do not help
  • I have no overclocking and have tried resetting and disabling overclocking in BIOS
  • I have updated the BIOS
  • enabling / disabling TLP does not help

I had no issues when I was using arch a few months ago so I know it worked at one point.

Really not sure what to try next.

It’s caused by linux-firmware regression and tracked in linux-firmware: amdgpu regression causing freezes, fix available upstream · Issue #466945 · NixOS/nixpkgs · GitHub

Thank you for the quick solution!

Using the older linux-firmware package specified in this comment does in fact solve my issue until the fix is merged here [Backport release-25.11] linux-firmware: 20251125 -> unstable-2025-12-18 by nixpkgs-ci[bot] · Pull Request #472939 · NixOS/nixpkgs · GitHub
